  • Is it professional to have funny looking logging messages

    - by JCH
    Hi, Recently I have joined a new project team where in the java application logs have logged messages in a non-formal way[can't think of suitable word]. here how they look :-) <message> for info messages :-| <message> for warn :-( <message> for error besides there's also ASCII art drawing , different one for each log when that particular service starts up or is killed .And there many more styles for certain application events. iam not sure if it has any significant overhead on the application or not. I would like to ask you folks if you come across such unique styles of logging messages or do you also practice any styles.what is your opinion about it. BR /jon

  • Deploying WPF application: .NET 3.5 issues

    - by Robbert Dam
    Hi all, Users around my country are currently beta-testing our application. My app uses WPF & Linq, so I need .NET 3.5 installation. On most system, everything works find, including automatic installation on .NET 3.5 on machines that do not have that installed yet. However, on one machine (XP SP2) my application does not run. The user reported no issues during .NET 3.5 installation (except for a process that need to close before the installer could continue - he closed the process and continued). The application crashes on startup. To debug this issue, I did the following: Have him reboot his machine Let him manually re-install the .NET 3.5 framework (no errors reported) Have him run a test WPF app that only displays a button - also crashes Let him send the .NET 3.5 installation logs - these are huge, don't now where to look Does anyone have strategy on how to debug such issues? I expect that this will occur more when the application is released..

  • Are there any existing batch log file aggregation solutions?

    - by Mohan Gulati
    I wish to export from multiple nodes log files (in my case apache access and error logs) and aggregate that data in batch, as a scheduled job. I have seen multiple solutions that work with streaming data (i.e think scribe). I would like a tool that gives me the flexibility to define the destination. This requirement comes from the fact that I want to use HDFS as the destination. I have not been able to find a tool that supports this in batch. Before re-creating the wheel I wanted to ask the StackOverflow community for their input. If a solution exists already in python that would be even better.

  • Invalidating ASP.NET FormsAuthentication server side

    - by Rob Walker
    I am experimenting with FormsAuthentication (using ASP.NET MVC2) and it is working fairly well. However, one case I can't work out how to deal with is validating the user identity on the server to ensure it is still valid from the server's perspective. eg. User logs in ... gets a cookie/ticket Out of band the user is deleted on the server side User makes a new request to the server. HttpContext.User.Identity.Name is set to the deleted user. I can detect this fine, but what is the correct way to handle it? Calling FormsAuthentication.SignOut in the OnAuthorization on OnActionExecuting events is too late to affect the current request. Alternatively I would like to be able to calls FormsAuthentication.InvalidateUser(...) when the user is deleted (or database recreated) to invalidate all tickets for a given (or all) users. But I can't find an API to do this.

I've tried to install the an ISAPI Filter written by Joe Pruitt. it works great on Windows Server 2003 32bit IIS 6.0, but seems to do nothing at all on windows server 2008 64bit IIS 7.0.

  • WCF - (504) The server did not return a response for this request.

    - by Sanjay Sen
    I have a JSONP WCF service,using back end as MySql.It is working properly when i run it locally with visual studio. Now we have hosted it in Windows Server 2003. Now there is very strange problem occurring.. When I do a request with fiddler which does not require much processing internally, it gives me result 200 OK with desired output as response, But when I do a request which requires some internal data processing, it gives me 504 error(gateway time out error). I also looked at C:\WINDOWS\system32\LogFiles to see if it logs any error but it shows ok result in fiddler request which is as follows: Fields: date time s-sitename s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) sc-status sc-substatus sc-win32-status 2010-04-07 10:08:06 W3SVC490896353 s-ip GET /InitialState.svc/GetInitialState reference=1&pageId=18 8080 - c-ip Fiddler 200 0 64 Can anyone please help me to resolve the problem ?? Or any ideas i can try to find out why it is happening ?? Any help will be appreciated...

  • Datacontracts property getter running twice

    - by user321426
    I have a set of data contracts that act as wrappers to base classes that we wish to expose. A quick example is: [DataMember] public List<decimal> Points { get { return sourceObject.ListPoints(); } private set{} } We have some other properties that we have to massage the data first (we are converting object graphs and need to guard against circular references). The issue that we are seeing is that this getter will fire twice, once within the service operation, then again during serialization. This is causing two problems: We manually add to collections, since this is running twice the collections are filled with dupes. If an exception is thrown during the second run, it happens outside of the try/catch in the operation, and does not throw a fault. The service throws a cryptic timeout message, and the only way to see the error is via WCF trace logs.

  • Facebook Connect showPermissionDialog callback fires before user can even see the dialog

    - by Chris Hiester
    I'm doing a Facebook Connect integration for a site and when the user logs in, I need to ask for some permissions so I use FB.Connect.showPermissionDialog. I use its callback to see if permissions were granted. If they are granted, I want to submit the form. Here's what my code looks like: $("#form3").live("submit", function() { FB.Connect.showPermissionDialog('email, offline_access', function(perms) { if (!perms) { location.href="http://www.mysite.com/logout/"; return false; } else { save_session(); } }); }); The problem is that the form submits before the user can even see the permission dialog. Has anyone seen this before?

  • TFS and code coverage for web application (MVC) assemblies not working

    - by Andrew
    I've got an MVC web application with associated controller tests that run under a TFS build as per normal. I can see the tests running and passing in the build log and they appear in the "Result details for Any CPU/Release" section of the build I also have a number of other assemblies with associated tests that are running in the same build. Tests are passing and the details are being shown in the results and logs just fine. I've enabled code coverage in the build script and the testrunconfig. The coverage is appearing for all assemblies EXCEPT the web application even though it looks like the tests have been run for it. Is there anything obvious that I have missed or some sort of work around that I need to do? I've searched around for a while and haven't found an answer. Has anyone got code coverage working for MVC web applications?

  • Need Users to Re-authenticate with NTLM

    - by Trey Carroll
    I'm NTLM (authenication="windows" in the web.config) with an asp.net mvc 2.0 site. Right now once a user logs in it keeps them logged in for weeks at a time. The use of the application is being opened up to users who share computers that use logged in service accounts. I need the site to reprompt each user for their AD credentials each time in order to handle these users. (Activity on the site must be linked to a uniquely identified user.) Thanks for any help that you can provide. Trey Carroll

  • Rails Routing Broken In Production - Caching of routes.rb suspected

    - by ming yeow
    Hi folks, i have an urgent problem. Essentially, my routing works on my localhost. But when i deployed this to production, the routes does not seem to work correctly. For example, given a new route "/invites" - sometimes i will get a 404, and sometimes it will work correctly. I suspect there is some caching going on somewhere, but i am not sure.

  • Hibernate, EHCache, Read-Write cache, adding item to a list

    - by Walter White
    Hi all, I have an entity that has a collection in it. The collection is a OneToMany unidirectional relationship storing who viewed a particular file. The problem I am having is that after I load the entity and try to update the collection, I don't get any errors, but the collection is never updated: Entity: @OneToMany(cascade = CascadeType.PERSIST) @JoinTable protected List<User> users; File Servlet @In private EntityQuery<File> File_findById; ... File file = File_findById(fileId); file.getUsers().add(user); session.update(file); Even though I call session.update(file) and I see stuff in hibernate logs, I don't see anything in the database indicating that it was saved.

    Hi. i have a j2ee web application running on spring framework and using log4j for logging. I have this line in my log4j.properties file. this will insert the logs in my database.

  • Interpretation of empty User-agent

    - by Amit Agrawal
    How should I interpret a empty User-agent? I have some custom analytics code and that code has to analyze only human traffic. I have got a working list of User-agents denoting human traffic, and bot traffic, but the empty User-agent is proving to be problematic. And I am getting lots of traffic with empty user agent - 10%. Additionally - I have crafted the human traffic versus bot traffic user agent list by analyzing my current logs. As such I might be missing a lot of entries in there. Is there a well maintained list of user agents denoting bot traffic, OR the inverse a list of user agents denoting human traffic?

  • How to store a user's password to another web application

    - by Horace Loeb
    I'm building a web application that shows users interesting visualizations of their Gmail activity (who they're emailing the most, etc). Obviously the user needs to give me his Gmail password to use the application, and I'm wondering how I should store it: Store the Gmail password in plaintext. Risky! Don't store the Gmail password at all; force the user to enter it every time he wants to sync data. Potentially inconvenient! Encrypt the Gmail password before storing it. The user's password to my application is the key. Something like (3) seems best, but with (3) I can only sync data when the user logs in (since I won't know his password to my application at any other time), which isn't ideal. I'd prefer a Mint.com-like solution whereby the user can click a button to sync data from Gmail at any time without re-entering his password (any idea how Mint accomplishes this without storing your banking passwords?)

  • Simple example of popup authentication with Facebook Graph API

    - by ensnare
    Trying to get Facebook to authenticate my users via a javascript popup. Right now, I have: <input type="button" value="Connect with Facebook" onclick="window.open('https://graph.facebook.com/oauth/authorize?client_id=XXXXXXXXXXX&redirect_uri=http://example.com/step2&display=popup')" /> But when the user logs in via Facebook, the popup just displays the Facebook.com homepage. I'd like for the popup to authenticate the user and go away so that I can start retrieving user data from the graph api. Is there a better / easier way to do this? Simple examples are appreciated. Thank you.

  • Troubles configuring SSL for an Apache host

    - by Ryan
    I configured it on Friday night and all worked well. Today for some reason it stopped working and I can't figure out why. When you goto the secure page it's acting like I have a self-signed certificate and I don't. I have the host configured like so ServerAdmin [email protected] DocumentRoot "/path/to/site" Servername www.mydomain.com ServerAlias mydomain.com DirectoryIndex index.cfm index.htm SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL SSLCertificateFile /etc/httpd/path/to/mydomain.com.crt SSLCertificateKeyFile /etc/httpd/path/to/www.mydomain.com.key SSLCertificateChainFile /etc/httpd/path/to/gd_bundle.crt Apache starts with no errors and I can't seem to find anything meaningful in any of the logs. It's got to be something minor but I can't seem to see it. It's an updated Centos/Apache VM. I have worn Google out.

  • use doctest and logging in python program

    - by Luke
    #!/usr/bin/python2.4 import logging import sys import doctest def foo(x): """ foo (0) 0 """ print ("%d" %(x)) _logger.debug("%d" %(x)) def _test(): doctest.testmod() _logger = logging.getLogger() _logger.setLevel(logging.DEBUG) _formatter = logging.Formatter('%(message)s') _handler = logging.StreamHandler(sys.stdout) _handler.setFormatter(_formatter) _logger.addHandler(_handler) _test() I would like to use logger module for all of my print statements. I have looked at the first 50 top google links for this, and they seem to agree that doctest uses it's own copy of the stdout. If print is used it works if logger is used it logs to the root console. Can someone please demonstrate a working example with a code snippet that will allow me to combine. Note running nose to test doctest will just append the log output at the end of the test, (assuming you set the switches) it does not treat them as a print statement.

  • Tomcat6 ignores logging.properties partially

    - by Bob
    I'm using Tomcat 6, and this is my logging.properties: handlers = org.apache.juli.FileHandler, java.util.logging.ConsoleHandler .level=FINE org.apache.catalina.core.ApplicationContext.level = OFF org.apache.juli.FileHandler.level = ALL org.apache.juli.FileHandler.directory = ${catalina.base}/logs org.apache.juli.FileHandler.prefix = mylog. java.util.logging.ConsoleHandler.level = FINE java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter On the one hand, Tomcat seems to read this file, as it correctly saves the logfiles with the prefix "mylog" and prints only messages with log-level FINE and above. On the other hand, it keeps on writing log messages like this: Jun 8, 2010 9:53:30 PM org.apache.catalina.core.ApplicationContext log SEVERE: Error writing messages ClientAbortException: java.net.SocketException: Broken pipe I actually wanted to suppress all log messages from this class, as they flood my logfile, and the error is irrelevant for me. So why is the following line ignored? org.apache.catalina.core.ApplicationContext.level = OFF Is there any other way to suppress the log output of this class?

  • dotnet nuke error

    Hi there im trying to degub a dot net nuke server error and im not sure where to start. I dnt have the code locally else I could debug (no that im familiar the dnn setup). This bug affects making cms updates to the site with the message 'A critical error has occured', I have been unsuccessfully trying to find out the cause and im finally throwing up my hands, I dont even need a fix , I just want to find out what is causing the error so I can provide an estimate for a fix and I can even seem to do that. I have tried looking at the logs but nothing seems to be logged about this error, is there a way to turn off custom error handling so as to get some clues as what the cause of this bug is? any suggestions would be welcome as i am getting desperate here :)

  • Grafting Scala 2.8 into a Netbeans NBAndroid Project...What steps am I missing?

    - by Michael Kohout
    Hi All; Due to Apple's recent T+C hijinks, I've become interested in developing for Android. Anyways, I'm trying to get a mixed-language Android 2.1 project going in Netbeans 6.8 (with the NBAndroid 0.10 plugin). The two languages being Java and Scala(2.8 head build). To give you a basic idea of what the app does right now, it's just a simple "Hello World" app. To get this to build, I've modified the projects's build.xml file: -- -injars ${scala-library}(!META-INF/MANIFEST.MF,!library.properties) -outjars "${build.classes.dir}/classes.min.jar" -libraryjars "${file.reference.android.jar}" -dontwarn -dontoptimize -dontobfuscate -keep public class * extends android.app.Activity -keep public class scala.xml.include.sax.Main** I've gotten the project so that it'll build, but it errors on startup in my Android Emulator(inside the emulator Android tells me my application has stopped unexpectedly). So my questions are: Does anyone see what I may be doing wrong? And is there any way to get access to the logs that the emulator must create? thanks Mike Kohout

To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

We do check the error logs and the operation require a FullTrust environment which currently fall under restriction on .NET Framewor k What should I do?
